FLUID-TURBINE.

Specification of Letters Patent.

Substitute for application Serial No. 9,430, filed February 19, 1915. This application flied October 26-, 1916. Serial No. 127,945.

0 all whom. it may concern:

Be it known that 1, human T. MANooUE, a citizen of the United States of America, and a resident of St. Louis, in the county of St. Louis and State of Missouri, have invented a certain new and useful Improvement in Fluid-Turbines, of which the following is a specification.

This invention relates to turbine'rotors, or, more particularly, to that class of rotors or wheels having a circular row or series of buckets or blades that are secured along the periphery or adjacent the periphery of the carrying disk or wheel where they are adapted to receive the impact or force of the prop lling fluid-pressure from a steam or other i n'cc nozzle located in convenient position f0 tangential-delivery of the emitting-jet int [he interior of each of the said buckets or blades as they successively advance in the remintions of the wheel.

'1 he object of the invention is to provide a t rbine wheel or rotor with semicircular buckets or blades that have forwardly-projot-ting side-walls with concave fore edges and one of such side-walls having at its in nor projecting-edge an outwardly-turned hook-formation that is preferably made on the same level as that .of the inner-edge of the opposite side-wall and adapted toengage, either a detachable-ring on the inner face of the peripheral-edge of the wheel, or

' an undercut groove or circumferential anbu ltels. a low only 0 nulus made in an inwardly shouldered orv thickened periphery of the wheel, and said buckets being adapted to be soldered along their registering and contacting concuvoconvex edges to unify all the buckets in circular or continuous ring-form around the wheel near its periphery, whereby they can all be put into and taken from place on the inner face of the wheel simultaneously for repairs. or for substitution, as desired.

The details of structure of the special foruof bucket and means of attachment will be fully hereinafter described and particularly -lined in the claims that then follow.

in l he a ompanying sheet of drawings,

Figure '1 i fragmentary elevation of the inner far o the. wheel showing my impl'uHPii circular, pcri )heral row or series of i the latter being shown broken open and in section, and a detachable auxiliary-ring being also shown along the inner line of said row of buckets to engage the lower, bent portion of the fastening-hooks of said buckets;

Fig. 2, a radial-section taken on the dotted-line a, a, of Fig. 1, showing one Way of securing my said improved buckets in place, (but omitting any elevation of the buckets that would otherwise appear in the background, and, also, omitting the fluid-pressure nozzle that is included in fragmentary form in said Fig. 1)

Fig. 3, a view similar to Fig. 2 but of what mi ht be herein deemed my preferred form of ucketfastening; and

Fig. 4, a pers )ective view showing several of the nproved buckets assembled together as they appear in their intended registeringcontact for use.

1 indicates the circular body-portion or rotor-disk having an integral lateral, annular peripheral-rib 2 (see Fig. 2), or an annular rib-formation 3 back of or adjacent its periphery (see Fig. 3), and a circular, continuous row or series of propulsionbuckets 4: along or adjacent the said periphery where they are duly located, as customary, to obtain and develop the greatest percentage of driving-force.

5 indicates the ordinary nozzle for tangentially delivering or directing the fluidpressure, such as steam or the like, into the said buckets as they successively advance into its discharge-path in the rotation of the wheel.

Each bucket is composed of a semicircular pressure-impinging fore or body-portion 6, side checks or walls 7 and 8, and a single, lateral or outwardly-turned hook-formation 9, the latter having its bent portion 10 extending from the side-Wall 8 and on the same plane as that of the inner edge of the side-wall 7 of the bucket, as best seen in Figs. 2 and 3, and thereby giving to the tip of the nozzle 5 the greatest lateral play that it, by chance, may have in relation to said inner, fluid-pressure inlet-edge of the bucket and avoiding collision with the hook in case it should rojcct below said inner or lower plane of tiie bucket.

Each of the side-walls 7 and S is provided with a semi-circular or concave edge that is adapted to snugly fit-in contact with and be duly soldered to the convex tune of the hodyportion 6 of the next sueeeeding hueket 4 no as to etfeet tight joints along the entire cireular, continuous row or sfillt'l-i of buckets.

The radial or outer part of each of the hooks 9 of the buckets engages an lnulereut channel or eireun'it'erential groove 10 made in the inner rorner or angle of the periph eratril- 3' l-ig. 2), such roove being somewhat wider than the thie mess of the metal in said radial part'of the hook whereby less friction and labor are ei'ieonntered in the insertion of the hooks when placing the buckets along the rim of the wheel, but the said radial part must fit anngly, however. against the tune of the outer wall of the groove and thereby obviate any undue vlhration, looseness, rattle or lateral play in the festenirig-eonnoi-tion. The planetace of the side-wall 8 of each hueket t' llltttls flatly and firmly with thizt ot' the lateral, peripheral rih A, and the hnekets are thin; unifornd x, seated and held in place without the Ilttt'tw sity of heing otherwise mechanically secured, the aforesaid soldering making tight joints between the buckets and practically unifying all the buckets in a single, composite, eontinuoue; ring that isnt onee strong, rigid and eiu'luring, for the tt rbine purposes desired.

The centrifugal forge idevelopedin the Speed of the rotor veryfreadil sustains the assembled eirciilar ring of ,nekets in place, with their hookg in attaching-engage ment; with the rear-grooved ripheralrrib, hut, for an extra. safe-gun against: any undue collapse of said rirg'irlai ring -of buckets, I provide an auxiliary or eniergeney ring 1] that is detuehaldyreenred in place on the tare of the rotor-disk l he means of serewa l2, so that ita outer. fare mutants -with the tlanhwerse part of the, hooks and allows no looaenvrs or |la that would other \\l,\t' only cause rattle and wear.

In this form of l'nieket-fastening, on a removable peripheral-ring, an entire set of contimuinslyronneeted buckets can be applied or removed bodily from the rotordisk for repairs or rapid substitutionwhen desired and. if preferred, the ring 14. can be made in a ninnher of segmental parts or seelions so that slurh aeelions can be removed therefrom without detrimentto the buckets and while an of the latter are in 11g repaired or otherwise handled, the rim 1% thus not eneuinhering the handling .0 the hueketa during such n pa-ii'sand, also being adapted for net in connecting another or ready, -#uhntitutfe eireular set of asenrbled lnu-ketn without any delay on-the jol'ni of wheel that I show in Fig. 3. in assembling the buckets, in "the form of devioemen in Fig 3, eae'h bucket/is hooked in, place,.one
